   AGORA — style.css
   A human-first digital public square.
   Mobile-first, vanilla CSS. No frameworks, no build step.

   Breakpoints (mobile-first, min-width unless noted):
     ≤480px   phone       — tuned in section 21 (max-width overrides)
     ≤768px   tablet      — hamburger nav, single-column layouts
     ≥769px   desktop nav — inline links + CTA
     ≥1024px  wide        — two-column hero, three-column gallery

   Palette (shared with the Agora app + logo):
     ink navy surfaces · cyan signal · emerald status ·
     indigo/cream from the logo mark
